Day 11 #ArtAdventCalendar: Happy birthday to trailblazing US #astronomer Annie Jump Cannon (1863 – 1941), here with her stellar classification system which sorted stars based on spectral types, revealing their temperature from hot blue to cool red stars: O,B,A, F, G, K & M. Named the Harvard Classification after the university, her tremendous contribution was less visible. 🧵

Eldest of 3 daughters of Delaware shipbuilder/state senator Wilson Cannon & Mary Jump, Annie’s mom taught her the constellations & encouraged her to pursue her own interests. She studied physics with Sarah Frances Whiting, 1 of few US women #physicists at the time, at Wellesley & became valedictorian in 1884. She returned home, worked various jobs, & published her photos over next decade. She lost most of her hearing possibly due to scarlet fever. 🧵2/
